Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio selective call receiver, and in particular, it has a reception message processing function for providing information that is easy for the user to see by displaying the received message with information added thereto. Wireless selective call receiver.

[0002]

2. Description of the Related Art Currently, in a radio selective call receiver,
Receivers with a display function that not only notify the call by ringing, but also decode the message signal transmitted subsequently to its own calling number and display it on the display unit attached to the receiver terminal are widely used. There is.

In particular, a numeral display type radio selective call receiver which composes a message only by combining a number from 0 to 9 and some symbols can easily send a message from an ordinary telephone terminal. Since the content of the message is limited to a telephone number or the like and is often about 10 to 20 characters, the air time is not so long. The numerical display type radio selective call receiver having such characteristics makes the most of the advantages of the radio selective call system and is most widely used.

FIG. 3 shows a signal format of the POCSAG system which is a typical signal system handled by the numeral display type radio selective call receiver, and FIG. 4 shows 4-bit data handled by the POCSAG system. In the conventional radio selective call receiver,
The message data transmitted in the signal format of FIG. 3 is decoded according to FIG. 4 and displayed on the display unit.

[0005]

However, in the above-described conventional radio selective call receiver, for example, when the telephone number "012-345-6789" is to be transmitted as a message, "2" and "5". Followed by "-"
You must put in a signal that corresponds to (hyphen). From the telephone terminal, for example, an input operation such as "* 2" is required. This kind of operation is not only troublesome, but also causes incorrect input.

Further, in the case of this example, if only numbers are transmitted, 10 characters are transmitted, and in the POCSAG system described above, 2 words of data are transmitted, but by adding 2 characters of "-", 3 words of Data will be sent, and airtime will increase.

[0007] On the other hand, in the above example, if the message is sent without adding "-", the sender side can easily input and the air time can be reduced, but the receiver carrier displays the received message without "-". Therefore, there was a problem that it became difficult to read.

The present invention has been made in view of the above-mentioned circumstances, and the transmitting operation on the transmitting side (calling side) is simple, the air time is reduced, and the radio waves can be effectively used, and the receiver can be used. It is an object of the present invention to provide a radio selective call receiver that can provide a display that is easy for the wearer to see.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a radio selective calling receiver according to an embodiment of the present invention. In FIG. 1, a radio signal modulated by a selective call signal and a message signal accompanying it is received by an antenna 1,
It is amplified and demodulated by the wireless unit 2.

The demodulated baseband signal is bit-synchronized and word-synchronized in the decoding section 3, and further error-corrected according to a predetermined coding method.

On the other hand, the own calling number stored in the calling number storage unit 4 is read into the decoding unit 3 via the control unit 5,
It is compared with the received selective call signal. If they match as a result of the comparison, a message signal following the selective call signal together with the match signal is transmitted to the control unit 5.

In the control unit 5, the speaker 9 and L are sent via the alert driver 8 to inform that the reception has been made.
An alarm is output to ED10. After detecting the coincidence of the selective call signals, which output device is used and how to issue (or temporarily hold) the alarm depends on the setting of each receiver.

The control unit 5 stores the received message signal in the message storage unit 6 at the same time, and the LCD
The message is displayed as character information on the LCD display unit 12 via the driver 11. In FIG. 1, a switch 7 is prepared for these alarms, operations such as resetting the display and rereading the display.

In the present embodiment, the transmitted message signal is information "0123456789" consisting only of numbers, whereas the LCD display section 12 displays "0".
12-345-6789 ", and two"-"s are inserted. The control unit 5 edits such a message signal and provides a display that is easy to see as a telephone number, for example.

Next, a specific method of editing the message signal in the control unit 5 will be described in detail with reference to FIG. As shown in FIG. 4, when the address (selective call signal) and the message are received (101), it is judged whether the function according to the present invention is applied or not by the received address (102). Of the plurality of addresses that the receiver has, which address the message received by which this function is applied is stored in the calling number storage unit 4 as a designated address.

If it is the address to which this function is applied, the pointer is moved to the lower digit of the message (103) and the digit number counter N is reset to zero (104). Next, the data A indicating which digit the "-" should be inserted is set (10
5).

It is judged whether there is a character above the digit currently pointed to by the pointer (106), and if there is a character, the pointer is shifted to the upper digit and the digit counter is incremented by 1 (107). If this counter N matches the designated digit number A (108), "-" is inserted into the message (109). Here, the data A is set, for example, by first setting A = 4, inserting “-” once, and then setting A = 3.

If there is no character above the digit pointed to by the pointer, the message signal is stored in the message storage section and displayed on the LCD display section (110). The same applies when the address is not the one to which this function is applied (11
0).

In the above embodiment, whether or not this function is applied is determined by the received address.
It is also possible to provide a judgment bit at the beginning of the message. Furthermore, it is common to use "()" in addition to "-" insertion as a method of displaying the telephone number.
It is extremely easy to change to such a display.

In the case of the United States where the telephone number system (the number of digits of the area code and the number of digits of the local code) is unified, this embodiment can be adopted as it is. If the number system differs depending on the region, such as in Japan, it has a character string table of area codes so that the "-" insertion position can be determined. Specifically, a character string table is prepared beforehand in the form of a memory storing the area code inside or outside the control unit, and the character string at the beginning of the message and the character string in the character string table are stored. Compare. If the strings match, insert "(" and ")" before or after the string at the beginning of the message, or insert "-" after the string at the beginning of the message. Display the area code. In this case, the insertion of "-" between the station number and the number is performed according to the procedure shown in FIG.

[0022]

As described above, according to the radio selective calling receiver of the present invention, a code that serves as a numeral delimiter such as "-" is automatically inserted in a received message containing only numerals. The transmission on the calling side is easy, the effective use of radio waves is promoted, and there is an effect that a display that is easy for the wearer to see is provided.
